USB Type‐C Test Adapter User Manual (Preliminary)
Introduction This user’s manual documents the USB Type‐C Plug and Receptacle Test Adapters (USBC‐TPA‐P and USBC‐TPA‐R) and the associated USBC TPA Low‐Speed Adapter Board. The two test adapter types, shown in Figures 1 and 2, test USB Type‐C interface cables, hosts and devices against the USB Type‐C Standards and Compliance Specifications. The TPA‐P and TPA‐R test adapter assemblies allow easy access, via SMA connections, to measure or inject data signals. The test adapters also provide access to USB DP/DN, CC1, CC2, VBUS and Ground, via an 8‐position low‐speed connector. Additionally, the user can access VBUS and Ground through a 2‐position Sense connector. Mating 8‐position and 2‐position connector housings and contact terminals are supplied with the test adapters to connect these signals to a wiring assembly provided by the user. NOTE: To avoid damaging the cables, use the handling techniques described in the Care and Handling section before making any connections or configuring a test setup. Always use a static‐safe workstation when performing tests, as explained in the “Electrostatic Discharge Information” section.

The USB Type‐C Test Adapter Care and Handling Precautions The USB Type‐C Test Adapter requires careful handling to avoid damage. Improper handling techniques, or using too small a cable bend radius, can damage the coaxial cable connections within the adapter housing or the cables themselves. This can occur at any point along the cable. To achieve optimum performance and to prolong the USBC‐TPA’s life, observe the following handling precautions: CAUTION 1: Avoid Torque Forces (Twisting) While individual coaxial cables within the test adapter have some rotational freedom, twisting the USBC‐TPA as a unit, with one end held stationary, may damage or severely degrade performance. Adherence to Caution 5 (below) helps to avoid twisting. CAUTION 2: Avoid Sharp Cable Bends Never bend coaxial cables into a radius of 26 mm (1‐inch) or less. Never bend cables greater than 90°. Single or multiple cable bends must be kept within this limit. Bending the USBC‐ TPA cables less than a 26mm (1‐Inch) radius will permanently damage or severely degrade test adapter performance. CAUTION 3: Avoid Cable Tension (Pull Forces) Never apply tension (pull forces) to an individual coaxial cable that is greater than 2.3 kg (5 lbs.). To avoid applying tension, always place accessories and equipment on a surface that allows adjustment to eliminate tension on the USBC‐TPA and cables. Use adjustable elevation stands or apparatus to accurately place and support the USBC‐TPA. CAUTION 4: Connect the USBC‐TPA First To prevent twisting, bending, or applying tension to the coaxial cables when connecting a USBC‐TPA, always attach the USBC‐TPA to the device under test (DUT) or cable under test before attaching any SMA connectors. Carefully align the USBC connectors and then gently push the connectors together until fully seated. If the USBC‐TPA must be turned or twisted to make connection to the DUT, avoid using the USBC‐TPA housing alone to make this occur. Try to distribute the torque forces along the length of the test setup and cabling. If this is not possible, it is recommended to first loosen or disconnect the SMA connections at the USBC‐TPA, make the connection to the DUT and then re‐tighten or attach the test equipment leads. NOTE: Only grip the test adapter housing when inserting or extracting the USBC‐TPA to or from the DUT. Pulling directly on the USBC‐TPA cables or using them to insert the USBC‐TPA may cause damage. CAUTION 5: Carefully Make SMA Connections To connect the USBC‐TPA SMA connectors, follow these steps: 1.
Hold the cable stationary by grasping the cable at the black heat‐shrink section near the SMA connector.
2.
Insert the mating SMA barrel and hand‐tighten the free‐spinning SMA nut onto the connector while avoiding pulling, bending, or twisting the USBC‐TPA coaxial cable.

3.
The USBC‐TPA SMA connectors have flats that accept an open‐end 1/4‐inch or 6.5mm wrench. When attaching instrument cables to the USBC‐TPA, it is recom‐ mended that the USBC‐TPA SMA connectors be mechanically held and the test leads be tightened to the equipment manufacturer’s torque recommendations, normally 5 in‐lbs., using a 5/16‐inch open‐end wrench. If the test set‐up requires repositioning, first loosen or disconnect the SMA connections to avoid twisting, bending, or tension. NOTE: A drop in signal amplitude by half or 6dB during the testing of a channel may indicate that a cable has been mechanically pulled free of coaxial cable connections internal to the assembly. This could be determined by checking if the cable has any lateral play relative to the TPA. This would only occur when the TPA has exceeded the pull force as specified within the mechanical specification. If the cable cannot be re‐seated, the test adapter will need to be sent back to the factory for service.
CAUTION 6: Independently Support Instrument Cables or Accessories Excessive weight from instrument cables and/or accessories connected to the USBC‐TPA can cause damage or affect the test adapter performance. Be sure to provide appropriate means to support and stabilize all test set‐up components.

General Test Adapter, Cable, and Connector Observing simple precautions can ensure accurate and reliable measurements.
Handling and Storage Before each use of the USBC‐TPA, ensure that all connectors are clean. Handle all cables carefully and store the USBC‐TPA in the foam‐lined instrument case when not in use, if possible. Do not set connectors contact end down. Install the SMA protective end caps when the USBC‐TPA is not in use.
Visual Inspection Be sure to inspect all cables carefully before making a connection. Inspect all cables for metal particles, scratches, deformed threads, dents, or bent, broken, or misaligned center conductors. Do not use damaged cables.
Cleaning If necessary, clean the connectors using low‐pressure (less than 60 PSI) compressed air or nitrogen with an effective oil‐vapor filter and condensation trap. Clean the cable threads, if necessary, using a lint‐free swab or cleaning cloth moistened with isopropyl alcohol. Always completely dry a connector before use. Do not use abrasives to clean the connectors. Re‐ inspect connectors, making sure no particles or residue remains.
Making Connections Before making any connections, review the “Care and Handling Precautions” section. Follow these guidelines when making connections: Align cables carefully Make preliminary connection lightly To tighten, turn connector nut only Do not apply bending force to cable Do not over‐tighten preliminary connections Do not twist or screw‐in cables Use an appropriately sized torque wrench (depends on SMA gender), and do not tighten past the “break” point of the torque wrench (normally set to 5 in‐lbs.)

Electrostatic Discharge Information Protection against electrostatic discharge (ESD) is essential while connecting, inspecting, or cleaning the USBC‐TPA test adapter and connectors attached to a static‐sensitive circuit (such as those found in test sets). Electrostatic discharge can damage or destroy electronic components. Be sure to perform all work on electronic assemblies at a static‐safe work station, using two types of ESD protection: Conductive table‐mat and wrist‐strap combination Conductive floor‐mat and heel‐strap combination When used together, both of these types provide a significant level of ESD protection. Used alone, the table‐mat and wrist‐strap combination provide adequate ESD protection. To ensure user safety, the static‐safe accessories must provide at least 1 MΩ of isolation from ground. Acceptable ESD accessories may be purchased from a local supplier. WARNING: These techniques for a static‐safe work station should not be used when working on circuitry with a voltage potential greater than 500 volts.

Calibration Through De‐Embedding The USB Type‐C Test Adapters are fully passive components. Therefore, calibration compensating for the losses must occur within the test instrumentation that drives the USB Type‐C receiver or looks at the response of the USB Type‐C transmitter. Wilder Technologies is in the process of creating USBC‐TPA Touchstone S4P files at this time. These files will soon be available to de‐embed the electrical length and losses within the TPA up to the Type‐C connector interface pads. (Contact Wilder Technologies, support@wilder‐ tech.com, for status and availability of the S4P files.) Once available, the Touchstone S4P files enable the test engineer to compensate for the last four of the following six repeatable, systematic errors that occur when moving the reference plane: Signal leakage effects: Directivity errors Signal leakage effects: Crosstalk errors Reflection effects: Source Impedance Mismatching errors Reflection effects: Load Impedance Mismatching errors Bandwidth effects: Receiver Transmission in Test Equipment errors Bandwidth effects: Receiver Reflection‐tracking in Test Equipment errors These errors are corrected on each port. Refer to the Instrument Manual for instructions on the instrument’s specific de‐embedding process. NOTE: The reference plane is the boundary, both physically and electrically, between the calibrated and un‐calibrated portions of the circuit. Everything outside the reference plane is considered part of the DUT. Any instrument that does not use calibration or de‐ embedding of the test fixture defines the DUT as the total of externally connected components. If the de‐embedding file is not used, all of the USBC‐TPA and associated coaxial cables, as well as cables connecting the TPA assembly to the test instrument, would be a part of the DUT. Non‐repeatable errors, such as drift or random errors, can be reduced but not corrected. Drift errors aggregate over time or with environmental changes such as temperature shift. To eliminate drift errors, perform an instrumentation‐level calibration. A random error cannot be corrected through calibration since the error occurred randomly. Random errors are typically associated with either test instrument noise or test repeatability problems. Reduce test instrument noise by increasing source power, lowering the IF bandwidth, or averaging results over multiple sweeps. Reduce test repeatability problems through the use of a torque wrench or, again, by averaging over multiple sweeps.

USBC TPA Low‐Speed Adapter Board The USBC TPA Low‐Speed Adapter Board facilitates the low‐speed connectivity and signal routing between the USBC‐TPA‐P or the USBC‐TPA‐R test signals, such as CC1, CC2/VCONN, VBUS, DN and DP, and the required test setup configuration. The board allows the connection of a USB Type‐C Power Delivery Controller through a USB Type‐C receptacle connector on the board to assert the various power delivery modes through the TPA for testing. The USBC TPA Low‐Speed Adapter Board also provides high‐speed connectivity for the USB Type‐C SBU lines via board edge SMA connections to the test fixture. Various voltage sources (VBUS, VCONN), can be used to emulate the DFP (Downstream Facing Port) source. See the “User Model” section of this document for examples of test setups. See page 32 of this User Manual for the USBC TPA Low‐Speed Adapter Board schematic.

USB Type‐C Test Adapter User Manual (Preliminary)
Introduction This user’s manual documents the USB Type‐C Plug and Receptacle Test Adapters (USBC‐TPA‐P and USBC‐TPA‐R) and the associated USBC TPA Low‐Speed Adapter Board. The two test adapter types, shown in Figures 1 and 2, test USB Type‐C interface cables, hosts and devices against the USB Type‐C Standards and Compliance Specifications. The TPA‐P and TPA‐R test adapter assemblies allow easy access, via SMA connections, to measure or inject data signals. The test adapters also provide access to USB DP/DN, CC1, CC2, VBUS and Ground, via an 8‐position low‐speed connector. Additionally, the user can access VBUS and Ground through a 2‐position Sense connector. Mating 8‐position and 2‐position connector housings and contact terminals are supplied with the test adapters to connect these signals to a wiring assembly provided by the user. NOTE: To avoid damaging the cables, use the handling techniques described in the Care and Handling section before making any connections or configuring a test setup. Always use a static‐safe workstation when performing tests, as explained in the “Electrostatic Discharge Information” section.

The USB Type‐C Test Adapter Care and Handling Precautions The USB Type‐C Test Adapter requires careful handling to avoid damage. Improper handling techniques, or using too small a cable bend radius, can damage the coaxial cable connections within the adapter housing or the cables themselves. This can occur at any point along the cable. To achieve optimum performance and to prolong the USBC‐TPA’s life, observe the following handling precautions: CAUTION 1: Avoid Torque Forces (Twisting) While individual coaxial cables within the test adapter have some rotational freedom, twisting the USBC‐TPA as a unit, with one end held stationary, may damage or severely degrade performance. Adherence to Caution 5 (below) helps to avoid twisting. CAUTION 2: Avoid Sharp Cable Bends Never bend coaxial cables into a radius of 26 mm (1‐inch) or less. Never bend cables greater than 90°. Single or multiple cable bends must be kept within this limit. Bending the USBC‐ TPA cables less than a 26mm (1‐Inch) radius will permanently damage or severely degrade test adapter performance. CAUTION 3: Avoid Cable Tension (Pull Forces) Never apply tension (pull forces) to an individual coaxial cable that is greater than 2.3 kg (5 lbs.). To avoid applying tension, always place accessories and equipment on a surface that allows adjustment to eliminate tension on the USBC‐TPA and cables. Use adjustable elevation stands or apparatus to accurately place and support the USBC‐TPA. CAUTION 4: Connect the USBC‐TPA First To prevent twisting, bending, or applying tension to the coaxial cables when connecting a USBC‐TPA, always attach the USBC‐TPA to the device under test (DUT) or cable under test before attaching any SMA connectors. Carefully align the USBC connectors and then gently push the connectors together until fully seated. If the USBC‐TPA must be turned or twisted to make connection to the DUT, avoid using the USBC‐TPA housing alone to make this occur. Try to distribute the torque forces along the length of the test setup and cabling. If this is not possible, it is recommended to first loosen or disconnect the SMA connections at the USBC‐TPA, make the connection to the DUT and then re‐tighten or attach the test equipment leads. NOTE: Only grip the test adapter housing when inserting or extracting the USBC‐TPA to or from the DUT. Pulling directly on the USBC‐TPA cables or using them to insert the USBC‐TPA may cause damage. CAUTION 5: Carefully Make SMA Connections To connect the USBC‐TPA SMA connectors, follow these steps: 1.
Hold the cable stationary by grasping the cable at the black heat‐shrink section near the SMA connector.
2.
Insert the mating SMA barrel and hand‐tighten the free‐spinning SMA nut onto the connector while avoiding pulling, bending, or twisting the USBC‐TPA coaxial cable.

3.
The USBC‐TPA SMA connectors have flats that accept an open‐end 1/4‐inch or 6.5mm wrench. When attaching instrument cables to the USBC‐TPA, it is recom‐ mended that the USBC‐TPA SMA connectors be mechanically held and the test leads be tightened to the equipment manufacturer’s torque recommendations, normally 5 in‐lbs., using a 5/16‐inch open‐end wrench. If the test set‐up requires repositioning, first loosen or disconnect the SMA connections to avoid twisting, bending, or tension. NOTE: A drop in signal amplitude by half or 6dB during the testing of a channel may indicate that a cable has been mechanically pulled free of coaxial cable connections internal to the assembly. This could be determined by checking if the cable has any lateral play relative to the TPA. This would only occur when the TPA has exceeded the pull force as specified within the mechanical specification. If the cable cannot be re‐seated, the test adapter will need to be sent back to the factory for service.
CAUTION 6: Independently Support Instrument Cables or Accessories Excessive weight from instrument cables and/or accessories connected to the USBC‐TPA can cause damage or affect the test adapter performance. Be sure to provide appropriate means to support and stabilize all test set‐up components.

General Test Adapter, Cable, and Connector Observing simple precautions can ensure accurate and reliable measurements.
Handling and Storage Before each use of the USBC‐TPA, ensure that all connectors are clean. Handle all cables carefully and store the USBC‐TPA in the foam‐lined instrument case when not in use, if possible. Do not set connectors contact end down. Install the SMA protective end caps when the USBC‐TPA is not in use.
Visual Inspection Be sure to inspect all cables carefully before making a connection. Inspect all cables for metal particles, scratches, deformed threads, dents, or bent, broken, or misaligned center conductors. Do not use damaged cables.
Cleaning If necessary, clean the connectors using low‐pressure (less than 60 PSI) compressed air or nitrogen with an effective oil‐vapor filter and condensation trap. Clean the cable threads, if necessary, using a lint‐free swab or cleaning cloth moistened with isopropyl alcohol. Always completely dry a connector before use. Do not use abrasives to clean the connectors. Re‐ inspect connectors, making sure no particles or residue remains.
Making Connections Before making any connections, review the “Care and Handling Precautions” section. Follow these guidelines when making connections: Align cables carefully Make preliminary connection lightly To tighten, turn connector nut only Do not apply bending force to cable Do not over‐tighten preliminary connections Do not twist or screw‐in cables Use an appropriately sized torque wrench (depends on SMA gender), and do not tighten past the “break” point of the torque wrench (normally set to 5 in‐lbs.)

Electrostatic Discharge Information Protection against electrostatic discharge (ESD) is essential while connecting, inspecting, or cleaning the USBC‐TPA test adapter and connectors attached to a static‐sensitive circuit (such as those found in test sets). Electrostatic discharge can damage or destroy electronic components. Be sure to perform all work on electronic assemblies at a static‐safe work station, using two types of ESD protection: Conductive table‐mat and wrist‐strap combination Conductive floor‐mat and heel‐strap combination When used together, both of these types provide a significant level of ESD protection. Used alone, the table‐mat and wrist‐strap combination provide adequate ESD protection. To ensure user safety, the static‐safe accessories must provide at least 1 MΩ of isolation from ground. Acceptable ESD accessories may be purchased from a local supplier. WARNING: These techniques for a static‐safe work station should not be used when working on circuitry with a voltage potential greater than 500 volts.

Calibration Through De‐Embedding The USB Type‐C Test Adapters are fully passive components. Therefore, calibration compensating for the losses must occur within the test instrumentation that drives the USB Type‐C receiver or looks at the response of the USB Type‐C transmitter. Wilder Technologies is in the process of creating USBC‐TPA Touchstone S4P files at this time. These files will soon be available to de‐embed the electrical length and losses within the TPA up to the Type‐C connector interface pads. (Contact Wilder Technologies, support@wilder‐ tech.com, for status and availability of the S4P files.) Once available, the Touchstone S4P files enable the test engineer to compensate for the last four of the following six repeatable, systematic errors that occur when moving the reference plane: Signal leakage effects: Directivity errors Signal leakage effects: Crosstalk errors Reflection effects: Source Impedance Mismatching errors Reflection effects: Load Impedance Mismatching errors Bandwidth effects: Receiver Transmission in Test Equipment errors Bandwidth effects: Receiver Reflection‐tracking in Test Equipment errors These errors are corrected on each port. Refer to the Instrument Manual for instructions on the instrument’s specific de‐embedding process. NOTE: The reference plane is the boundary, both physically and electrically, between the calibrated and un‐calibrated portions of the circuit. Everything outside the reference plane is considered part of the DUT. Any instrument that does not use calibration or de‐ embedding of the test fixture defines the DUT as the total of externally connected components. If the de‐embedding file is not used, all of the USBC‐TPA and associated coaxial cables, as well as cables connecting the TPA assembly to the test instrument, would be a part of the DUT. Non‐repeatable errors, such as drift or random errors, can be reduced but not corrected. Drift errors aggregate over time or with environmental changes such as temperature shift. To eliminate drift errors, perform an instrumentation‐level calibration. A random error cannot be corrected through calibration since the error occurred randomly. Random errors are typically associated with either test instrument noise or test repeatability problems. Reduce test instrument noise by increasing source power, lowering the IF bandwidth, or averaging results over multiple sweeps. Reduce test repeatability problems through the use of a torque wrench or, again, by averaging over multiple sweeps.

USBC TPA Low‐Speed Adapter Board The USBC TPA Low‐Speed Adapter Board facilitates the low‐speed connectivity and signal routing between the USBC‐TPA‐P or the USBC‐TPA‐R test signals, such as CC1, CC2/VCONN, VBUS, DN and DP, and the required test setup configuration. The board allows the connection of a USB Type‐C Power Delivery Controller through a USB Type‐C receptacle connector on the board to assert the various power delivery modes through the TPA for testing. The USBC TPA Low‐Speed Adapter Board also provides high‐speed connectivity for the USB Type‐C SBU lines via board edge SMA connections to the test fixture. Various voltage sources (VBUS, VCONN), can be used to emulate the DFP (Downstream Facing Port) source. See the “User Model” section of this document for examples of test setups. See page 32 of this User Manual for the USBC TPA Low‐Speed Adapter Board schematic.
